Four Seasons Calistoga Hotel Pool & Spa

Calistoga, CA


PACE provided the project design services for the five-star Four Seasons Calistoga Hotel and custom single-family homes located on approximately 21 acres of land in Calistoga, Napa County, California. These services include four in-ground skimmer pools, including a zero-edge entry family pool and infinity-edge adult pool in the pool building, a partially raised and partially flushed residential pool in the residence area, and a presidential pool located in the villas. Three structural spas were also designed by PACE, including an adult spa and a family spa in the pool building, both containing wall emitters to give them a fountain look, and a main spa in the spa garden.

PACE rehabilitated an existing pond by creating a new north stormwater detention pond. To add to the Four Seasons Calistoga Hotel’s natural modern look, PACE included the design of two fountains in the lodge area, two steam decks, and two boulder water features in the spa garden. Other architects participating in this project are O’Bryan Partnership Architects., MKK Consulting Engineer Inc., and Bald Mountain Development.
